I'm getting started with persistent volumes and k8s. Im trying to use a local folder on my RH7 box w minikube installed. Im getting the error:

0/1 nodes are available: 1 node(s) didn't find available persistent volumes to bind.

The issue is in your persistent volume, your persistent volume has following node selector:

nodeAffinity:
    required:
      nodeSelectorTerms:
      - matchExpressions:
        - key: kubernetes.io/hostname
          operator: In
          values:
          - my-node

where your PV is trying to bind on node whose name is my-node, which it couldn't find as there is no node with that name. Please check your node-name using:

kubectl get nodes

And put the node name at the place of my-node and it will work. Hope this helps.

If you work with docker-desktop on windows, so try this:

  1. Create dir in wsl:
docker run --rm -it -v /:/k8s alpine mkdir /k8s/mnt/k8s
  1. Create storageclass,vol,vol claim,pod:
kind: StorageClass
apiVersion: storage.k8s.io/v1
metadata:
  name: local-storage
provisioner: kubernetes.io/no-provisioner
volumeBindingMode: WaitForFirstConsumer
---
apiVersion: v1
kind: PersistentVolume
metadata:
  name: local-storage
spec:
  capacity:
    storage: 50000Gi
  accessModes:
    - ReadWriteMany
  persistentVolumeReclaimPolicy: Retain
  storageClassName: local-storage
  local:
    path: /mnt/k8s
  nodeAffinity:
    required:
      nodeSelectorTerms:
        - matchExpressions:
            - key: kubernetes.io/hostname
              operator: In
              values:
                - docker-desktop
---
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: postgredb
  namespace: xxx
spec:
  storageClassName: local-storage
  accessModes:
    - ReadWriteMany
  resources:
    requests:
      storage: 100Gi
---
apiVersion: apps/v1
kind: StatefulSet
metadata:
  labels:
    app: postgres
  name: postgres
  namespace: xxx
spec:
  serviceName: postgres
  selector:
    matchLabels:
      app: postgres
  template:
    metadata:

    spec:
      containers:

          volumeMounts:
            - mountPath: /var/lib/postgresql/data
              name: postgredb
      volumes:
        - name: postgredb
          persistentVolumeClaim:
            claimName: postgredb
